Ask Smalley. Our engineers are always on call
with free design consultation, downloadable CAD

entire instrument is shut down until it
can be replaced. Users struggle with
the loss of revenue associated with
downtime, which encourages them to
choose instruments that they perceive
as offering higher reliability.
The drives for the newest generation of syringe pumps are designed
to ensure a minimum life of 5 million
cycles. In fact, ongoing life testing of a
population of these pumps has shown
they are capable of operating continuously for three years and have exceeded
25 million cycles.
Syringe pumps generally employ a
shear valve to direct fluid flow between
aspirate to dispense operations. Unfortunately, shear valves are notorious for
leaking and seldom achieve a million
cycles without problems, so even if the
drive is still operating after a million
cycles, there is a good chance the
instrument will need to be shut down to
replace the shear valve. In contrast, the
newest syringe pump designs employ
a long-life rocker isolation valve that is
rated to 10 million cycles.
For engineers working for manufacturers of clinical diagnostic and analytical
chemistry instruments, new pump options are emerging that promise higher
performance on multiple levels. As pump
manufacturers come to accept that
their customers are demanding higher
precision, accuracy, resolution, and long-term reliability, as well as a non-pulsing
operation at low flow levels, more of
these manufacturers will eventually make
the investments necessary to catch up
with the needs of today’s demanding

Bemis Healthcare Packaging has engineered a child resistant pouch
for the safe disposal of transdermal patches and inhalers. Utilizing
our expertise in blown film technologies, laminating and pouch
conversion, we have successfully engineered this unique, protective
solution. This pouch is designed to help prevent accidental exposure to highly toxic drugs
such as fentanyl, a potent opioid pain reliever. According to the Food and Drug Administration, young children and pets can easily remove discarded medicines from household trash.
FDA and other federal agencies recommend following instructions on medication labels
and talking to health care professionals about safe storage and disposal of medicines.
